.To all whom it may concern:

Be it known that STEPHEN PALMER, deceased,late a citizen of the UnitedStates, and a resident of Tro in the county of Rensselaer and State 0New York, did in his lifetime, together with lVIARCUS M. WATERMAN, ofTroy, Rensselaer' county, New York, invent certain new and usefulImprovements in A paratus for Making Fibrous Conduits, [O of wlhch thefollowing is a specification filed by us, WILLIAM G. PALMER, executor ofthe estate of said STEPHEN PALMER, deceased, and MARCUS M. W TERll IAN,residents of Troy, New York, itizens of the United States; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Our invention relates to an improved a aratus for making fibrouscondults, the oli ect of the inventlon being to provide improvements ofthis character in which the tube moves vertically and has alternate I z5 layers of-braiding and pitch applied thereto automatically; and theinvention consists in certain novel features of construction andcombinations and arrangements of arts, as will be more fully hereinafterdescri ed, and

' 3o pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation,illustrating our improvements. Fi 2 is a plan view of one of theitch-pots. Ti thel in longitudinal section of the former 5. Fi 6 is aview in elevation, illustrating the tube formation; and Fig. 7 is a viewin longitudinal section, showing the formation of the sev- 4o eral tubelayers.

1 represents a frame of any suitable construction in which a verticalmandrel 2 is secured and com rises a longitudinally grooved or serratedr0 so shaped to reduce friction and rendering eas the longitudinalmovement oftthe tube t ereon.

3 representsa spool or sup ly-roll of ta e ,4, from which the tape is felongitudina ly to the rod. and is curved into cylindrical form aroundmandrel 2 by a former 5 of general conical shape, having a cylindricalbore with g. 3 is aview in section on me a: 20 thereof. Flgsll and 5 areV16WS flared lower end and a triangular block 6 set in its lower end toproperly guide the 001% verging edges of the tape and prevent turning ortwisting of the tube on the rnandreL.-

The tube forn'led by cylindrically-curving tape 4 above former 5receives an open braiding 7, the thread being supplied from a series ofbobbins S on a rotary platform and properly guided to the tube-by theconical shape of the former. After receiving open braiding 7 the tubepasses up through an improved pitch-pot 9, (clearly shown in Figs; 3 and4,) which comprises a casting having a hollow steam-receiving chamber 1.in its bottom, and a gas or other fluid-burning coil 11 is located belowthe pot 9 to heat the-same by such means when desired. The pot has araised hollow central portion 12, through which the tube passes, and ismade with three (more or less) pairs of grooves 13=to receive brackets il, carrying pitch-applying wheels 15, and said brackets 14 are connectedby coiled springs 16 to hold the peripheries of the wheels against thetube. The wheels 15 are made with concave peripheries and are providedwith peripheral teeth or prongs 17 to engage the tube and insure theturning of the wheels and the supplying of a pitch coating thereto;Above pitch- 0t 9 the tube receives a fine braiding 1.8, w iich embedsitself in the hot pitch, the threads being supplied from bobblns 19 on arotary platform 20. The tube next passes through another pitchpot 21,similar to pitclrpo't 9, to receive another coating of pitch and. abovepot 21 re ceives another fine braiding 22, the threads being suppliedfrom bobbins 23 on a rotary platform 24*. The tube is then drawn over afeed-wheel 24, having a toothed concave periphery to insure the feedingof the tube, and is afterward given a waterproof covering 25 in anydesired manner.

It will be observed that our improved ap garatus is entirely automaticin its operation. he formation of the tube is continuous, permittin thetube to be cut off in any lengths desire A great many slight changesmight be made in the general form and arrangement of the parts describedwithout departing from 0111111V611t1011,.untlli61106 we won KOO itunderstood that 'We do not restrict ourselves to the precise details setforth, but consider ourselves at liberty to make such slight 'changesand alterations as fairly fall within the spirit and scope of ourinvention. Having fully described our invention, what we claim as new,and desire to secure by Letters Patent, is

1. In an apparatus of the character described, the combination of alongitudinally grooved or serrated mandrel, a former constructed tobring the longitudinal edges of a tape together around said mandrel toform a tube, means for feeding the tube so formed longitudinally of themandrel, means in the former to prevent turning or twisting of the tube,and means for applying layers orcoatings of braiding and pitch to thetube as it is fed along the mandrel.

2. In an'apparatus of the character described, the combination of meansfor form- 'inga tube and feeding it longitudinally, of a pitch-potthrough which the tube is passed, and wheels in said pot having theirperipheries against the tube and turned by the movement of the tube tosupply pitch thereto.

3. In an apparatus of the character described, the combination Withmeans for forming a tube and feeding it longitudinally, of a pitch-potthrough which the tube is fed, means for heating the pitch in said pot,and toothed wheels in said pot engaging the tube to apply a coating ofhot pitch thereto.

-4. n an apparatus of the character described, the combination withmeans for forming a tube and feeding it longitudinally, of a pitch pothaving a central opening through which the tube is passed, asteamchamber in the bottom of said pot, a series of brackets supportedin grooves in the pct,

wheels having concave and toothed peripheries supported by said bracketsand engaging the tubes and springs connecting the brackets and holdingthe wheels in engagement with the tube.

5. In an apparatusof the character 'described, the combination with avertical mandrel and means for forming a tape around the mandrel, ofmeans for braiding the tape on the mandrel and means for elevating pitchfrom a receptacle and depositing it on the braided tube, substantiallyas set forthv '6. In an apparatus of the character described, thecombination with a mandrel,.of

on yielding bearings for feeding or applying pitch to the tube,substantially as set -forth.

In testimony whereof we have signed this specification in the presenceof two subscribmg witnesses.
